I've recently started to learn about and practice with Teensy's audio library, and their companion shield. The reason that I have gone this route is that the Mozzi library uses lower fidelity DACs that result in too much noise, even though they … [Read more]

Recently completed is a step sequencer that combines many different subsystems to yield a nice sounding and playful platform. We hope that this provides enough documentation so that when I come back to this project, I can actually get up to speed … [Read more]

The Teensy 3.2 is an amazing small Arduino, and it uses a powerful ARM processor running at 96 MHz. One of the benefits of this part is that it has a multitude of sensor inputs (on the order of 12) that can be used as switches or similar … [Read more]

Amazon has a pair of very inexpensive on the ear headphones that I thought would be perfect for a variety of low fidelity uses where I did not want to bother with in the ear/earbud type transducers. Also, it provides a good balance of noise … [Read more]

I've switched to using Adobe's CC photo sharing facility for sharing photographs with others. Although you can not add text, you can show a nice 'light table' image of all photos at once, and you can then click on photos that you like.
Here are … [Read more]

Project for portable Arduino work that also allows integration and experimentation with BMP180 Barometric Sensor breakout board. It also has a pushbutton input and a photo transistor, and a voltage divider to measure current. I plan to use this in … [Read more]
